p2+6p+1=0

Solution for p2+6p+1=0 equation:

p2+6p+1=0

We add all the numbers together, and all the variables

p^2+6p+1=0

a = 1; b = 6; c = +1;
Δ = b2-4ac
Δ = 62-4·1·1
Δ = 32
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{32}=\sqrt{16*2}=\sqrt{16}*\sqrt{2}=4\sqrt{2}$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-4\sqrt{2}}{2*1}=\frac{-6-4\sqrt{2}}{2}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+4\sqrt{2}}{2*1}=\frac{-6+4\sqrt{2}}{2}
